GAS CHARGE
GAS CHARGING KIT
ALL NPK HYDRAULIC HAMMERS are furnished with the following gas charging kit. In
addition, a nitrogen tank and pressure regulator valve (not furnished with the hammer)
is required. These can be obtained from your local welding supply house. An optional
regulator valve, part no. 21101050 is available from NPK.
Be advised that when using special charge
adapter (g13) to adapt for the use of standard
NPK gas charge valve (g1), it is important to
make sure that pin (g14), bottom picture, is
not bent or damaged in any way. If pin (g14)
is bent or damaged, it may not be possible to
check the charge in the hammer. When the
standard NPK gas charge valve is coupled to
the adapter (g13), pin (g15) should move
downward approximately 1/8” as the T-handle
(g2) is turned clockwise.
NOTE: If the pin (g14) in the center of the NPK gas charge valve (g1) is
bent, checking and charging the hammer may not be possible.
